If you don't have Homebrew installed, go here https://brew.sh/ and install it.
Install homebrew tap:
brew tap MTG/essentia
Install compiling the code for the latest official release of Essentia
brew install essentia
Place two sets of .aif audio files in the audio folder, each file from first group containing A_ and from the second B_ in their name
A_1 and B_1, A_2 and B_2 etc. will be considered pairs. If you want another format, edit the file extension in ./src/analyseAudioFiles.
Cd to the project directory and run this shell script
sh runThis.sh
You will see data sets with extractor information and a plot folder with distances between each pair for each descriptor.
Example of distances:
